    Inside neutron stars we can find the weirdest and most dangerous substance in the universe: Strange matter. What is strange matter, how dangerous is it and what can it tell us about the origin of the universe?

  • Jesus Christ is coming! Repent & Believe the Gospel

    The Lord Jesus Christ is arriving soon.
    Jesus loves you, friends.
    My prayer is that this comment reaches one person that needs to read this.
    The Lord is for us, not against us.
    He is not angry at you, He truly loves you.
    He took our punishment upon Himself on the cross, He died so that we may live! 3 days later He arose again, assuring us of our redemption. Hallelujah!
    He promises He will never drive anyone away when they come to Him, so don’t let anyone or anything stop you from coming to Jesus today!
    All you need is faith as a mustard seed and sincere words from your heart.
    He will forgive you, make you new, deliver you from your sins and from the judgement headed to this earth.
    For all those that call upon the Name of The Lord shall be saved! (Romans 10:13)

    I love this episode. I had never heard of strange matter.
    I have a couple questions though:
    I also was thinking that while you say that it would be infectious, we have never witnessed such infection. And thus, we can sleep tight. However, can't that mean that there's something wrong with this theory, like strange matter isn't that stable? Or is it just that we think that neutron star collision is just incredibly improbable? Cause if such event started, the infection should exponentially accelerate, wouldn't it?
    Would these strangelets bend spacetime significantly around themselves?

    So strange quarks are not stable but strange matter is!
    Btw we know that strange quarks are not stable. Have we experimentally created them and observed their decay or did we come to know that theoretically?
    If we did create them experimentally, wouldn't that be a problem? Or are strange quarks not a problem since they are not stable and don't convert other matter into strange quarks/matter unlike strange matter, which happens to be made from the very same strange quarks?
